How do I take hardware inventory of Windows Servers in HomeGroup using Powershell? Servers are not in the domain.

systeminfo.exe is the command used to get the system information 

No Issue. domain not base... we need all are systems or server online... 

using WMI cmdlt.. must we are enabled "winrm services" from client or designation side. 

This PowerShell tool allows to inventory a list of Windows server. The most of the work is made with Windows Management Instrumentation calls (WMI Architecture) to retrieve the systems configuration before being injected in a SQL database.
